FRANK JASKOWIAK, OF ST. CLOUD, MINNESOTA.

BENCH 0R FLOOR DOG.

Application filed December 14:, 1921.

To all to hom-z't may concern:

Be it known that I, FRANK JASKOW'IAK, a citizen of the United States,residing at St. Cloud, in the county of Stearns and State of Minnesota,have invented certain new and useful Improvements in Bench or FloorDogs, of which the following is a specification, reference being had tothe accompanying drawings. r

, Considerable difliculty arises when hanging doors, windows and thelike, due to the necessity of planing the edges of the doors or windows,which cannot be done without the use of a second workman, to hold thedoor or window on its edge, unless a bench is installed for the purpose.ticularly true in the construction of new houses, as there are nobenches for such use.

The invention, therefore, has for its purpose the provision of a flooror bench dog of sufficient size to be fastened to the floor and providedwith clamps, to hold the door or window. sash on its edge, andsufficiently rigid, to permit the carpenter to properly plane the edgesof the door or window sash to make a proper fit, and to enable thehinges and locks to be applied. In fact the floor or bench dog holds thedoor or window sash substantially rigid, while the edge of the door isbeing channeled out to receive a lock, or it is to be made to receivethe hinge "rising supports and base member at one end, the uprisingmember being substantially the same as the base member, with theexception of an extension, which together with the base member areprovided with clamps, to be screwed toward and in contact with theopposite faces of the door or window sash, to hold the same in positionwhile its edge is being planed, so that the door or window will fitproperly in the easement.

Still another purpose is the provision of means 'forholding the upwardlyinclined edge in different adjusted positions, in ac cordance with thedoor or window to be supported.

further purpose involves the eonstr'uet Specification of Letters ?atent.

ing of the upwardly rising inclined member in two sections, one mountedin guides of the other and carrying the extension which in turn supportsthe upper clamps, so as to accommodate holding doors or window sashes ofdifferent sizes.

A still further purpose is the provision of means for holding onesection of the upwardly inclined member in different adjusted positionsrelatively to the inclined section of the member.

While the design and construction at present illustrated and set forthare deemed preferable, it is obvious that as a result of a reduction ofthe invention to a more prac tical form for commercial purposes, theinvention may be susceptible of changes, and the right to these changesis claimed, provided they are comprehended within the scope of what isclaimed.

The invention comprises further features and combination of parts, aswill be hereinafter set forth, shown in the drawings and claimed. 7

, In the drawings Figure 1 is a view in perspective showing the improvedfloor or bench dog constructed in accordance with the invention andarranged to support a door;

Figure 2 is a vertical sectional view, showing the upwardlyinclinedmember of the floor or bench dog, in a lowered position,

showing the sliding section extended;

Figure 3 is a sectional view on line 3-3 of Figure 2;

Figure 4 is a cross sectional view on line 4 -t of Figure 2; V

Figure 5 is a cross sectional view on line 55 of Figure 2 through theclamps; and

Figure 6 is a detailed view in elevation of the hinge connectionsbetween the extensible section 11 and the extension 30.

Referring to the drawings, 1 designates a base member of the floor orbench dog, which may be constructed of any suitable material, and may beany suitable shape or size, and is provided with lateral ears or lugs 2for the reception of screws or other fastening means 8, whereby the basemember may be secured rigidly in position.

One end of the base member has uprising supports l, in bearings ofwhich. fulcrum bolts 5 are mounted.

Pivotally mounted upon the fulcrum bolts are the lugs 6 of the pivotallysupported member Tthere being nuts mountedupon the bolts 5 to hold themin place.

The pivoted member 7 of .the 11001 or bench dog comprises two sections,the main section 9 (which is pivotally supported upon the bolts) and theextensible section 11, which is mounted in guides 12 of the section 9.The two sections 9 and 11 are provided with registering elongated slots13, which receive a bolt 14 including a wing nut 15, whereby theextensible section 11 may be extended and held in different positions.

Togglelinks 16 and 17 are provided on opposite edges of the two membersof the floor or bench dog. The toggle links 16 are pivotally mounted at18 on the edges of the base member, while the toggle links 17 arePiVQtally connected at 19 to the edges of the pivotally supported memberThe adjacent ends of the toggle links terminate in circular p a es 2 whih are p a y connected by means of the; bolt 22 including a wing nut 23,for holding the circular plates conceni ally t get e and or ba ing h toglinks in different adjusted ositions. In fact the adj acent faces of thecircular plates have radial grooves and teeth 24: to interengage, toinsure holding the toggle links in different positions.

The base member of the floor or bench dog at one end is provided withspaced arms 25, in bearings of which screws 26 are mounted, and areadapted to adjust axially toward each other. These screws 26 have Wingheads or thumb pieces 27, and their adjacent ends terminate in swivellymounted plates 28, adapted to engage the opposite faces of the door orwindow sash, to clamp the same in place, when the screws are adjustedtoward each other.

Hingedly mounted by means of an elongated bolt 29 to the section 11 isan extension 30. The bolt 29. has mounted thereon a coil spring 31, thearms 32 of which are connected at 33 to the section 1.1 and theextension 30, to hold the extension normally in alignment with thesection 11.

The extension is provided with a pair of arms 34: in which the screws 35are threaded for adjustment axially toward and from each other. Theadjacent ends of these screws have swivelly mounted plates 37, which areradially corrugated at 38 and are adapted to engage the opposite facesof a door or the rail of a window sash, to hold the'same in an uprightposition on its edge.

.lI hB sciiews of the arms of the extension have thumb pieces or wingheads 39, by which the screws may be adjusted toward and from eachother, to insure holding the door or window sash uprigli t.

In the use of the floor or bench "dog. the base member is first fastenedto the floor, then the pivotally supported member is djusted in itsdesired position. The door or window sash is then moved so that its endedge will engage between the arms of the base member andthe pivotallymounted extension 30, whereupon the clamping plates of the screws arebrought axially toward each other and in contact with the opposite facesof the door or sash. the screws are then tightened and the door or sashis held secure and in an upright position, after which the carpenter canproceed, without delay, to plane the edge of the door and apply thelocks and hinges thereto.

The invention having been set forth, what is claimed is x 1 1. In afloor or bench dog, a base member adapted to be secured to a stationarysupport, the opposite end of the base member having upstanding supports,a supporting member pivotally mounted upon said supports, saidpivotally-mounted member having a yieldablyrmountedextension, means forholding the pivotally mounted member in different positions pivotallyrelatively to the base member, the corresponding ends of the basevmember and the extension having axially alignedclamps, between whiehthedoor, window sash or the like may engage, whereby it may be planed. i

2. In a floor or bench dog, a base member to be secured to a stationarysupport, a door abutment member pivotally supportedupon the base member,the door abutment member having a hingedly mounted extension, saidcorresponding ends ,Of the pivotally mounted extension and the basemember having axially aligned clampingscrews, between which the door tobe planed engages, and means for holding the door abutment member indifferent adjusted positions.
